Dear Mr Wiggle,
How is Mrs Wiggle and all the little Wiggles?
1st Q;
The vinegar that contaminated your basic goop would not interfere unless it was a large enough amount to lower the PH a lot. If it was just a little it likely won't matter. You can always add more lime to get the PH back up.
2nd Q;
What I would do, is to spread your alcohol+cactus out in a big dish in the sun until all the alcohol has evaporated.
After that, it should behave just fine.
There may be some other ways to go about this. Maybe keep the alcohol and do FASI instead of
FASA [edit -- I meant to say FASW]? I do not have enough experience with those to know. Anyone else?
Hope that helps.
Regards,
AlZaBo
